SPECIFICATION forming part of Letters Patent NO. 707,657, dated August26, 1902.

Application filed March 3, 1902. Serial No. 96,499. (No model.)

To n/ZZ zotom, zit may concern.-

Beit known that LCORNELIUS VANDERBILT, a citizen of the United States,residing in the borough of Manhattan, city and State of Newv York, haveinvented certain new and useful- Improvementsin Locomotive-Boilers,o fwhich the following is a specilication, reference being had to theaccompanying drawings, form ing a part hereof.

This invention relates particularly to locomotive or other boilers whichare adapted for the use of oil as fuel and in which, there,- fore, twoor more furnaces or furnace-fines communicate with a commoncombustionchamber, from which the tubes extend forward, as usual.

The invention is particularly concerned with the furnaces andcombustion-chamber, and has for its object to providea structure whichshall be sufficiently strong to resist the pressure within the boilerwithout the use of stay-bolts.

The invention will be fully described here-' inafter with reference tothe accompanying drawings, in which- Figure l is a longitudinal centralsection of enough of a boiler to illustrate the application of thepresent improvement thereto. Fig. 2 is a transverse section on the line2'2 of Fig. l looking toward the rear.

The boiler-shell a may be of any suitable i form, that represented inthe drawings being well adapted for the particular use for which theboiler is intended. To the rear end of the shell the rear head b issecured in any suitable manner and itself receives and supports the rearends of the cylindrical corrugated furnaces or furnace-fines c, d, ande. Forward of the furnaces or furnace-fines is located the cylindricalcombustion-chamber f, which is made up of a cylindrical corrugated shellg, a flat circular rear head 71 which receives and supports the forwardends of the furnaces or furnace-lines c, d, and c, and the tube-sheett', in which the rear ends of the tubes 7c are secured as usual. Thecylin' drical combustionchamber is supported upon the bottom of theboiler-shell a, as by a'filling-piece Z, secured between the shell g ofthe combustion-chamber and the boiler-shell a, around registeringopeningsmandn, formed in the shell a and in the shell g, respectively.As the combustion-chamberjis cylindrical and corrugated, it issufficiently strong to withstand the pressure in the boiler without theuse of stay-bolts, which are commonly employed between the fire-box andthe boilershell and are essential when the fire-box or combustionchamber is made in the form hitherto usual. Furthermore,the cylindricalform of the combustion-chamber permits the arrangement of the furnacesor furnace-lines shown in the drawings, two being below the third, whichis centrally disposed, all of the lines being located within thecircumference of therear head of the combustion-chamber. Thisarrangement is obviously advantageous in the generation of steam. Thecylindrical form of the combustion-chamber also permits the f urnacesorfurnace-fines to have a large diameter, while the rear head of thecombustion-chamber is supported by the furnacelues in such a manner asto be capable of withstanding the pressure in the boiler.

I claim as my invention- In a locomotive-boiler,the combination with theboiler-shell and rear head, of a cylindrical, corrugated combustionchamber having a fiat circular rear head and three cylindrical,corrugated furnace-lines communicating with the combustion-chamber andsupported by the rear head of the combustion-chamber and the rear headof the boiler and located within the circumference of the rear head ofthe combustiolrchamber, one of the furnacelines being disposed above andbetween the other two, substantially as shown and described.

This speciflcation signed and witnessed this 1st day of March, A. D.1902.
